Grocery chain Meijer plans to accept both Apple Pay and CurrentC mobile payments, serving as the only major CurrentC partner refusing to shun Apple Pay. The store has 200 locations across five states in the Midwest, and while it isn't the most influential Merchant Customer Exchange (MCX) member, it's a clear sign that retailers want to give customers the chance to have more options while paying.

"We have had the technology in our stores to accept mobile wallets for several years now," said Frank Guglielmi, Meijer spokesman, in a recent statement to the media. "If a customer has Apple Pay capability, our hardware works with it. We don't plan to remove or disable these systems."

It's unknown if MCX will try to punish a member if they refuse to shun Apple Pay - but could be a sign of future efforts by retailers looking to appeal to as many customers as possible - though new partners that sign up for CurrentC could be fined because they are legally forbidden from accepting other rival systems.
